An Old school entertainment device, invented in the 1970's along with other whack stuff like the Abacus. It was a Loud Video Cassette that the whole street could hear in the machine. Was replaced by the VHS.

Anthony: Did you hear Kev Mac rewinding a porn clip from Benidorm on his Beetamax last night?

Quinthorp: Ha ha... the Beetamax is such a loud functional device... of course I heard it
